Figure 3 Histopathological features of the orbital mass indicate low-grade B-cell lymphoma of MALT type. (A) Low-power view (H&E stain, ×40) showing a dense lymphoid infiltrate with nodular architecture in orbital soft tissue. (B) High-power view (H&E stain, ×400) shows atypical lymphoid cells with irregular nuclei and scant cytoplasm, consistent with MALT lymphoma. MALT – mucosa-associated lymphoid tissue; H&E – hematoxylin and eosin.
